****伴侣1.1

软件名称： ****伴侣1.1
软件大小： 213 KB
应用平台： Win9x
软件类别： 游戏记牌器
发布主页： http://www.****.com
软件介绍：联众，边锋游戏牌类记牌器，注册后全部功能可用。
破解工具：ollydbg 1.08 ，W32DASM10，UltraEdit8.0，AspackDie，fi2.5
破解方法： 注册算法
朋友玩联众游戏，说有记牌器《****伴侣1.1》要注册才能玩够级，让我看看。他的注册方法有些独特，注册表验证，而且必须连接联众后才验证,分不同地方验证，而且必须用游戏ID，这就是说你只能用一个用户ID玩游戏。上网也没查到有注册机。自己动手吧。
先脱壳，aspack2.12，用AspackDie好脱。
用W32DASM反汇编，查找可疑字符串等。再用ollydbg 1.08调试，断点就好设了。

-----------------------------------------------------------------------
以上以为找到联众注册码，我们可以用它注册成功（边锋的注册差不多）。注意是“以为”！！！
注意用户名必须是联众注册用户名，我试用一下，但是游戏够级，梭哈等只显示记牌窗口不能记牌，不注册不显示记牌窗口。去他的主页论坛，好像也有人说不能用够级，而且是购买的正式注册用户。不知道是他的程序的bug，还是他设定的陷阱，我没有找到破解方法？如果按我的方法，那么每个用户可以有无数的注册码，显然不行吧？那就是还有问题没解决。
那么我想其实s2应该与用户名有对应算法，我动态调试没有找到，因为我不能上网，好像虽然成功写入注册表，但是它还需要验证，但可能需要上联众才能验证。我暂时无法解决。只好反编译看看。
*********************************************************************
用W32DASM反编译,查找可疑字符串，找到"联众校验 1 OK"
以下为联众校验的反编译部分，但是无法找到s2与用户名有对应算法，

再找，功夫不负有心人！
用W32DASM反编译,查找可疑字符串，"联众注册检测2通过"
找到以下为联众注册检测s2的反编译部分,这里是关键了！！！
连接联众后，从注册表读出注册信息，来到以下call：

终于找到了，连蒙带猜。
以下部分为注册机程序，delphi，联众经过验证。
边锋的我不玩，有兴趣的朋友可以自己作验证。

随想：是否可以找到他的连接联众时的断点，改变跳过或者跳到注册检测2部分，那我们就不需要上网
就可以动态调试他的检测部分了，是否可行？
有兴趣的朋友还可以试一下爆破，爆破点我已经注明，边锋的类似。
你可以注册你的所有游戏ID了。不知道爆破后是否所有游戏ID都能用呢？试试吧。我是累了。
